Scientists study whale's blow hole microbes with the help of a drone

Science
Oct. 10 (UPI) -- Scientists have for the first time surveyed the unique community of microorganisms -- the microbiome -- living inside the blowhole of a humpback whale. They did so with the help of a six-rotor hexacopter.Researchers with the Woods Hole Oceanographic Institution used a custom-built drone to collect blow samples, the moist breath exhaled by whales, from 17 humpbacks off the coast of Cape Cod and from nine humpbacks swimming near Canada's Vancouver Island. The scientists sequenced the genetic material found in the blow samples to identify the microbes living in each whale's respiratory tract."We were using the drone to take aerial images of the whales, so that we could assess body conditions," NOAA researcher John Durban said in a news release. "Because of the stable flight p...

Observations suggest black hole formation scenarios

Science
Aug. 23 (UPI) -- Scientists at the University of Birmingham have identified formation scenarios of black holes by observing gravitational waves.The study, published today in Nature, utilized the LIGO gravitational wave detector in 2015 and 2017 to make landmark observations of gravitational waves.Physicists found that the first detected gravitational waves observed in 2015 were produced during the final fraction of a second of the merger of two black holes to produce a single, massive spinning black hole.The first formation scenario researchers found was that black holes are spinning slowly leading to something different happening to stars that form black holes than those in Earth's galaxy. The second scenario was that black holes spin rapidly, similar to those in Earth's galaxy, but that ...
GST may not burn a hole in your pocket, but you will have to tighten purse strings

GST may not burn a hole in your pocket, but you will have to tighten purse strings

What we buy, how we buy and why we buy are questions that have for long fascinated anthropologists. But GST is expected to add a new twist to the tale of Indian consumerism. Under the new taxation regime fruits, vegetables, pulses, wheat, bread and rice are exempted from taxation even as chips, biscuits, butter, tea and coffee are attracting higher taxes. So, would that make families to make healthier choices at the supermarket? Cited as the "single largest taxation reform" in independent India, GST is set to change taxation for every sector — from real estate to vehicles to consumer durables to branded goods to luxury items. For a middle class family that earns between Rs 50,000-Rs 80,000 a month, the impact on the monthly budget will not be more than a few hundred rupees. For those

China Eastern Airlines plane lands with large hole in engine

World
June 12 (UPI) -- A China Eastern Airlines plane sustained a major engine failure and returned to Sydney with a massive hole in its engine, witnesses said.The hole in the engine's nose cowl, the metal shroud at the front of the engine, was visible to the 221 passengers aboard the Airbus A330-220 on Flight MU736 to Shanghai as they departed the plane. No one was injured in the incident.The passengers said they heard what sounded like an explosion, and smelled a burning odor.Australia's Transport Safety Bureau launched an investigation focused on the Trent 700 engine manufactured by Rolls-Royce. A statement from Rolls-Royce said it was "aware of the incident and will be working closely with relevant partners to understand the cause of the issue."The engine failure closely resembles a similar ...
